SETTING MEC ANISM To all w it may camera Be it known that I, Li' NAnUs Bennie, a

Wayne, inthe county of Allenvand State of Indiana, have invented new and useful Improvements in, SettingMechanism for Ind 1- eating-Registers, of which the following 1s a specification.

My invention is a setting inechanism for counters, indicators and the like, such as the counters, registers and meters on measuring It provides means easily, yet

quickly and'positively establishingfadefinite predetermined relation between the pointer or indicatorand the dial or scale as a starting point preliminary to the normal opera-- tion of the machine to which the counter .or indicator is attached. This fsetting operation, as" it may be called, is accomplished by graspin the movablepart and traversing it rapi ly clock-wise toward the intended setting position. When reaching said position the motion is automatically arrested and upon relaxing thegrasp the pointer or indicator remains in position, but free, when the functioning machine is then operated, to

continue the motion just arrested.

It is immaterial whether the pointer or indicator moves with relation to a fixed dial or scale, or the dial or scale moves with relation to a fixed pointer or indicator.

"The hereinafter described and illustrated embodiment of my invention, may be regardedas anim rovement upon the device shown in Letters to me on June 18, 1918 ;-although the principle involved may be advantageously applied to' other mechanisms used for various purposes. y

In'the particular embodiment of my in vention selected for illustration, my invention is shown in relation to acounter for a measuring pump, in which the pointer is the movable part, and the dial is stationary.

Figure 1 is a front view of a counting device; with my iinproved setting mechanism added; partially exposed to view by breaking away a portion of the dial or scale, the rest being shownin dotted lines.

Referring now to the drawings, P is a stationary part of the pumpto which the cas' ing G ofthe setting mechanism is attached by screws 0 or many other suitable manner.

Afixeddial A is attachedto the front of the casing C by screws a. A ratchet wheel D which is journaled in the: center of the casl ing'C, has a central bossd extending through the center of the dial Aand to this boss is fixed a pointer E by a screw 6 and the'dowelpin 6 Th pointer E hasa handle 6 for convenience in rotating. Ratchet teeth d? are formed on the inner side of'the flanged edge (1 of the atchet wheel D.

e "To a moving part of the pump. (not shown) as, the crank shaft or any part driven therebg:

, at 7. The lever F is journaled at f to the ratchet wheel D, at its axis. A stud 'f fixed in the lever F, carries a pawl f adapted to engage the ratchet teeth d to rotate the ratchet WheelD when the leverF is oscillated; while a pawl 0 carried on the stud c fixed in the casing C also engages the teeth 03 and preventsreverserotation of the ratchet wheel D.

The ratchet wheel D has on its periphery fsition other than at zero, for instance 12 if 12 gallons has last been pumped; before beginning to make delivery to another customer, grasp the handle 6 and rotate the pointer clock-wlse rapidly until the pointer is attached a link 7 pivoted to the nearly reaches zero, when the position of the double pawl and ratchet wheel lugs will be as shown in Fig. 3, because lug d has raised the end of the double pawl, bringing the end 9 automaticall into position for engagement with the approaching lug (P; which takes place and is maintained temporarily by frictional contact, so that at zero the position of these parts will be as shown in Fig. l, preventing further forward rotation of the pointer, until removal of hand pressure through the pointer from between the end 9 of the double pawl and the lug (Z permits the double pawl to gravitate automatically to its normal position, shown in Fig. 1.

Normal operation of the pump will then cause the pointer to correctly indicate the number of gallons delivered on the next count from zero as the point ofbeginning.

l claim as my invention, and desire to secure by Letters Patent of the United States: 1. In an indicator capable of rotation in one direction only, the combination of a rotatable element and a non-rotatable element adapted together to indicate quantity, the rotatable element being driven by the mechanism to which the indicator is attached; a

cam on the rotatable element whose receding portion forms two positioning shoulders disposed in opposition to each other; the nonrotatable element constituting resetting means with engagementfaces disposed in opposition to each other, one of said faces adapted to be brought into engagement upon rotation of the cam with its opposing shoulder by action of the cam on the nonrotatable element, arresting rotation at the starting point on the indicator, and then to drop into the receding portion of the cam and free said face of said shoulder.

2. In a ratchet driven indicator, the combination of a rotatable element and a nonrotatable element adapted together to indicate quantity, the rotatable element being driven by the mechanism to which the indicator is attached; a cam on the rotatable element having a receding portion contiguous to a positioning shoulder, said receding portion forming an escapement detent; an oscillating element constituting resetting means and having a face adapted to be moved into engagement with said shoulder at the starting point by the pressure of the cam on another portion of said oscillating element, whereupon said other portion of the oscillating element enters the receding portion of said cam and trees said face of said shoulder.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
